Zevra Therapeutics, a Rare Disease Therapeutics Company, Files Preliminary Proxy

CELEBRATION, FL, February 27, 2023 – Zevra Therapeutics, Inc. (NasdaqGS: KMPH) (“Zevra” or the “Company” and formerly known as KemPharm, Inc.), today announced it has filed its preliminary proxy statement with the U.S. Securities and Exchange Commission (the “SEC”) in connection with the Company’s 2023 Annual Meeting of Stockholders (“Annual Meeting”), which is scheduled to take place on April 25, 2023. Stockholders do not need to take any action with respect to the 2023 Annual Meeting at this time.

In its preliminary proxy statement, Zevra announced that the Board has nominated three directors for re-election at the Company’s Annual Meeting — Richard W. Pascoe, David S. Tierney, M.D., and Christopher A. Posner.

With the re-election of these serving directors, the Zevra Board will comprise seven highly qualified individuals, five of whom are independent and each of whom is actively engaged in overseeing Zevra’s transformation into a commercially driven rare disease therapeutics company. The three incumbent directors collectively bring decades of biotech and pharmaceutical experience, both as senior executives and as members of public company boards.  These directors bring valuable experience across a range of relevant areas, including drug development, medical, finance, business development and commercialization, which are essential to drive continued momentum and stockholder value as the Company executes on its transformative growth strategy.

The Zevra Board and management team remain focused on delivering life-changing treatments to people with rare conditions and their families awaiting better options, while driving enhanced value for all stockholders. The Company recently launched Zevra as its new corporate name and brand — an important step forward in its transformation from a prodrug development company with an out-licensing model, into a commercially-driven company intently focused on giving its promising rare disease therapeutic candidates a fighting chance to reach patients and improve their quality of life.

Having changed its corporate name from KemPharm to Zevra Therapeutics, the Company will begin trading under the new ticker symbol “ZVRA” on the Nasdaq Global Market on or about March 1, 2023.

“Our name change and new Zevra brand are key steps in advancing our company’s focus on rare disease therapeutic research, development and commercialization,” said Matthew R. Plooster, Chairman of the Zevra Board of Directors.  “Under the leadership of our new CEO, Richard W. Pascoe, we believe Zevra is better positioned today than at any point in its history as we work toward our key priorities to secure regulatory approval for our pipeline assets, build top-tier commercial capabilities and enhance our pipeline through targeted business development transactions. We are confident in the team, in our strong financial foundation and diverse portfolio of multiple clinical programs, and in our ability to deliver value in 2023 and beyond.”

In its preliminary proxy statement, the Company disclosed that a stockholder, Daniel Mangless, is proposing the election of three other candidates to the Board of Directors. The Zevra Board believes that electing any of these candidates would diminish the overall quality of, and experience represented on, the Board. The Board recommends that stockholders reject these efforts by Mr. Mangless to advance his own interests, which the Board believes are not in the best interests of the Company and all Zevra stockholders.

Additionally, Mr. Mangless has submitted a proposal to adopt a resolution at the Annual Meeting that would repeal any provision of the Company’s Amended and Restated Bylaws in effect at the time of the Annual Meeting that was not included in the Company’s Amended and Restated Bylaws in effect as of January 1, 2023. The Board also believes this proposal is opposite the interests of all Zevra stockholders.

Travis C. Mickle, Ph.D., a co-founder and longtime executive and director of the Company, said, “I fully support Zevra’s strategy to evolve into a commercial organization focused on developing transformational, patient-focused therapies for rare diseases with limited or no treatment options. This is an exciting time for the Company with much opportunity ahead.  Proxy battles can be costly and distracting, and as such, I intend to vote in favor of the Zevra slate.  I trust that the Board and stockholders will work together to find a reasonable path forward as we have in the past.”

Zevra currently has two FDA-approved products, highlighted by AZSTARYS^®, a once-daily product for the treatment of ADHD in patients aged six years and older, and continues to support its ongoing commercialization by partner Corium, Inc. The Company continues to make progress with the updated New Drug Application (“NDA”) for arimoclomol as a treatment for Niemann-Pick disease type C (“NPC”), which is expected to be filed as early as the third quarter of 2023. In addition, in December 2022, Zevra initiated its Phase 2 clinical trial investigating KP1077 as a treatment for idiopathic hypersomnia (“IH”), a rare neurological sleep disorder, with interim efficacy and safety data expected as early as the third quarter of 2023 and full Phase 2 data available as early as year-end 2023.

With $102.9 million in cash, cash equivalents and long-term investments as of December 31, 2022, Zevra expects its available capital will fund its development plans and extend its cash runway into 2026. The Company believes the numerous milestone opportunities anticipated for 2023 and beyond will drive continued growth at Zevra.

Zevra’s preliminary proxy materials can be found on the SEC’s website at www.sec.gov. The Company’s definitive proxy materials will be mailed to all stockholders eligible to vote at the 2023 Annual Meeting. Stockholders may receive materials, in the mail or otherwise, from Daniel Mangless. The Zevra Board recommends that stockholders discard any proxy materials from Daniel Mangless and vote using the WHITE proxy card they will receive as part of the definitive proxy materials that will be delivered by the Company.

With unique, data-driven clinical, regulatory, and commercialization strategies, the Company is overcoming complex drug development challenges to bring much needed therapies to patients.

Arimoclomol, Zevra’s orally-delivered, first-in-class investigational product candidate for the treatment of Neimann-Pick type C (“NPC”), has been granted orphan drug designation, Fast Track designation, and rare pediatric disease designation for the treatment of NPC by the U.S. Food and Drug Administration (“FDA”), and orphan medicinal product designation for the treatment of NPC by the European Medicines Agency (“EMA”).

KP1077 is Zevra’s lead clinical candidate being developed as a treatment for idiopathic hypersomnia (“IH”) and narcolepsy.  KP1077 is comprised solely of serdexmethylphenidate (“SDX”), Zevra’s proprietary prodrug of d-methylphenidate (“d-MPH”).  KP1077 has been granted orphan drug designation by the FDA for the treatment of IH, and the U.S. Drug Enforcement Agency (“DEA”) has classified SDX as a Schedule IV controlled substance based on evidence suggesting SDX has a lower potential for abuse when compared to d-MPH, a Schedule II controlled substance.
